books and similar articles.

It is an object of this invention to provide a portable reading lamp ofthe' class-'described which may be quicldy and easily attached to abool: or similar article in such position thatfthe reader will haveadequate light directly von'the matter without interfering' with the mal'tons in the vicinity.

object to provide a portable lamp d which requires nooutside powersource but An tv iich the lamp and its power source fori-.fi aseli-contained unit when. not inxusewith no exposed wires and with theslamp .bulbrprotected from breakage.

It is a further object to provide a portable-lamp as described in whichthe cover for the self-contained unit also serves as a .mounting meansand' as a reflector when the lamp is in use.

In the drawings:

Figure l is an elevational View of the unit shown when not in use, withparts being broken away for clarity;

Fig. 2 is a cross-sectional view taken along the line 2-2 of Fig. l;

Fig. 3 is a plan View of the unit with the parts being broken away forclarity; and

Fig. 4 is an elevational View of the cover assembly and a portion of thecontainer assembly shown in cross section, the assemblies being in theirseparated condition.

The unit comprises, in general, a cover assembly I I and a containerassembly I2 which, when the device is not in use, are in internttedrelation as shown in Fig. 1. The container assembly comprises a casingI3, preferably of rectangular shape, which may be constructed of plasticor similar insulating material. Resting within the casing is a batteryI4, the dimensions being such that the battery ts between front and rearwalls I5 and I5 respectively of the casing and against one side wall Il.A cable storage space I8 is provided between the battery and oppositeside wall I8. The bottom 2l of the container may have integral therewithan upstanding ridge 22 to retain the lower end of the battery in itsproper position, and walls I5 and I6 may be provided with elongatedraised portions 23 to hold the adjacent sides of the battery flushtherebetween. A battery retaining plate 24 is provided immediately abovethe battery to retain it against upward movement. This retaining plateis held in position by means of lugs 25 on the inner .tion of the pagesand without disturbing' surfaces of casing walls i5 and It, and theretaining plate is provided withrecessed portions 2S so that it may beremoved from its locked position by a leftward sliding movement as shownin Fig.` 3. The plate is also provided with. an

. apertured portion 2l for access to the `battery terminals. Recesses 23arefprovided in the side walls adjacent the upper edge of casing AI3 towretainfthe cover unitrwhen in-its inoperative position, aswillbe laterdescribed. The upper edge of rearwall I5 is further provided with anelongated recessed portion '2Q for receiving portions of. the coverassembly.

Cover1 assembly H is movable betweenv an inoperative positionsurmounting the casing and an operative position attached to a book orsimilar article. This assembly comprises a shellflike member 3Q having adome SI oi slight downward concavity, front and rear walls 32 and 33respectively, and side walls Elfi and te. Wall S3, of greater heightthanthe other. Walls,.has pivotally mounted thereon a pair of clips 36and. 3'.' `by v such means as rivetsii .and 3Q. These clips .are

preferably of springlilre material and are movable between aninoperative position as shown in Fig. l and an operative position asshown in Fig. 4, substantially normal to the dome 3| and in which thecover of a book or similar article may be rmly engaged between the clipsand wall 33, the wall being in underlying engagement with the article.Intermediate the two clips is a lamp bulb socket 4I, which holds a bulbl2 in a position spaced below the dome 3 i, The socket may be held inplace by means oi a bracket 43 and rivet 44. Plates d5 and t6, separatedby insulators 47 and d8, serve to connect the lamp socket to electricalconductors is and 5I respectively. These conductors are part of a cable52 to the other end of which is attached a plug having a handle 53 andprongs 54 for insertion in battery terminals 55. Bracket d3 may be provided With a cable grip 56 for preventing strain at the ends of theconductors. Cover member 30 is further provided with a shelf 5l betweenthe dome 3l and the walls, the shelf being adapted to rest on the upperedge of the casing when the two assemblies are united. Side walls 34 and35 are provided with projections 58 which snap into recesses 28 when thecover member is placed on the casing.

The device, when in its inoperative position, will be assembledsubstantially as shown in Fig. 1. As will be seen when in thiscondition, cable 52 will be coiled and will reside within space i8adjacent the battery, and the plug will also be casing and the clips orthe lamp socket when the' cover is put on.

When it is desired to use the device for reading or similar purposes,the cover assembly Il is removed from container assembly I2, clips 36and 31 are swung downwardly, and the cover assembly is mounted on thecover of the book or other article by means of the clips, as heretoforedescribed. Cable 52 and its attached plug are removed from space I8 bymeans of handle 53, and prongs 54 of the plug are inserted in terminals55 of the battery, thus energizing the lamp. It will be observed that inthis condition the container assembly may be remotely positioned fromthe reader if desired. It will also be noted that concave dome 3l of thecover member 29 will serve as a reflector for the reading lamp, and thatfront and rear Walls 32 and 33 and side walls 34 and 35 will serve toconiine the rays from the lamp to the immediate vicinity of the printedmatter, thus preventing disturbance of persons who may be in thevicinity.

What is lclaimed is:

1. In a device of the class described, a casing of rectangular form forsupporting an electric power source, a cover for said casing made fromsheet metal having a continuous central dishshaped portion presentinginwardly toward the casing when the cover is attached thereto, adownwardly extending flange about the dishshaped portion for receivingthe casing, the flange at one side of the cover projecting a substantialdistance beyond the ange on the other three sides thereof, a receptaclefor a lamp supported on the extended ange, a cable connecting the lampto the power source Within the casing, and a pair of ngers pivoted onsaid extended flange for securing the cover to a book in position tohave the lamp within the cover direct the light thereunto, said coverbeing releasably attached to said casing for completely hiding saidngers, lamp and cable from view.

2. In a lighting device for illuminating the pages of a book, comprisinga rectangular casing for supporting an electric power source, a cablealso supported within said casing, a cover of rectangular shape having acontinuous central portion from which a flange extends downwardly on allsides for extending over the open end of the casing forming a closuretherefor, the ange on one side of the cover being of substantial lengthas compared to the length of the ange on the other three sides thereof,a lamp socket secured to said extended flange, a lamp in said socket,connecting means between one end of said cable and said socket in amanner to be in series with the filament of said lamp. and a pair ofngers pivotally secured to said extending flange by which the cover maybe secured to a book, said fingers and lamp being enclosed within thecasing When the cover is applied thereto.
